T0 all whom, it may 0072007417,:

Be it known that I, J AMEs BOWER, a citizen of the United States, residing at Forest City, in the county of Mason and State of Illinois, have invented a new and useful Thrash- This Iinvention relates to grain-separators;V

and its object is to provide a Separator possessing superior advantages in point of simplicity, ease of operation, and general lefficiency. p

In the drawings, Fignre 1 is a side view of the machine. Fig. 2 is a view of the opposite side. Fig. 3 is a top View of the separator, the top of the easing being removed. Fig. 4 is a rear end view of the same. Fig. 5 is a Vertical longitudinal sectional view. Fig. 6

is a Vertical transverse sectional View, taken through the roek-arn1s for Operating the grainconvcyer and the shoe, and through the grainspont,on the line x w, Fig. 5. Fig. 7 is a perspective detail View illustrating the construction and arrangement of the separating-rakes.

Referring to the drawings, A designates the frame or casingof the machine, which may be mainly of any suitable construction, and is preferably mounted upon wheels O for convenience in transportation.

D is the feeding-cylinder, which is provided with the usual projecting teeth, E, and is carried by a transverse rotary shaft, F, having bearings in the sides G G of the casing, and projecting therefrom. This cylinder D is arranged over a convergent inclined bottom, H, having a transverse slot, I, through which the grain separated from the straw can pass onto the shoe. A snitablebox or hopper, J, is arranged at this front end of the casing, which opens into the cylinder-chamber, as shown.

On one end of the shaft F is fixed a bandwheel, K, or other suitable mechanism, by`

formed with a series of counterbalanced cranks,

U, each of which is arranged to carry a pair of longitudinal strips or bars, V V, between which' are secured upwardly-projecting fin gers V, and which are secured together by cross pins or bolts X.

Y is a transverse guide-rack arranged be tween the sides of the casing, and at the front end of the latter, preferably on a plane lower than the bearings of the shaft T. This rack comprises two horif/,ontal strips, Z Z, between which are secured Vertical. guide-pins A2, which enter between the pairs of strips V V. The rack Y is preferably arranged under the bottom H, and supports and guides the front ends of the longitudinal riddle-bars B2, that are formed by the strips V V and the fingers XV. The shaft T is rotated by an endless band, C2, which passes around the pulley L, over a band-wheel, D2, on the said shaft T, and around a band-wheel, E2, fixed on the end of a transverse shaft, F2, that is ]'ournaled at the bottom rear end of the casing, and has its ends projecting from the latter. As this counterbalanced crank-shaft T revolves the riddle-bars B2 travel alternately up and down and forward and backward, half of the bars being up and moving toward the r'ear end of the :machine while the remaining bars are down and traveling toward the frontend of the machine. This inotion thoroughly separates and picks and scatters the bunches of straw as they come from the feeding-cylinder,

IOO

' segmental guide-slot, L2, in the side of the casing, and is secnred to the said grain-conveyer. A pitman, M2, extends from a crank, N2, 011 one end-of the shaft T to the top of 'one of these rock-arms 12, and thns the movemeno of the shaft T is transmitted to operate the grain-conveyer.

O2 is the shoe, which is arranged at the rear end of the grain-conveyer,and under the same. The shoe is swung upon pivoted rods P2 P2, and is reciprocated on the latter by means of inwardly-extending arms `Q2 Q2, that project from the lower portions of the rock-arms 12 12, and work through segmental guide-slots R2 R2 in the sides G G of the casing.

1t will be observed that the grain-conveyer is swung at its forward end and connected to the rock-arm at its rear end, and above the pivot of the latter, while the shoe is swung at its rear end, and is connected to the rock-arms at its front end, and below the pivot of said arms. By reason of this arrangement the conveyer and the shoe have connterbalanced movements. The bottom S2 of the shoe is inclined downwardly and forwardly to the transverselyarranged grain tronghor spont T2, and is provided at its top rear end with a transvcrse slot, U2, which opens into the transverselyarranged tailings trough or spont V2. tail end of the grain-conveyer G2 is provided with perforations 72, above the shoe, which facilitate the passage of the grain from the conveyer to the shoe, from which latter it passes to the grain-spont,while the chaif and tailings are driven by the blast from the fan to the rear end of the shoe and pass through the slot U2 into the tailings-spout. The grain-spont is hung at its ends from pivoted rods X2 X2. and is preferably provided with a centrallylpivoted bottom board, Y2, by which the grain can be deflected to either end of the said spout; The latter is reciprocated transversely by means of4 a rock-rod, Z2, jonrnaled at the side of the casing, and provided-with lateral arms A3 B2, respectively, at the top and bottom, and projecting at right angles to each other. The arm B3 is pivotally connected by a rod, O, with the grain-spout T2,while from the top arm,A'2,extends a forwardly-projecting pivoted rod, D72, to the lower end of the rockarm 12. The tailings-spont is reciprocated in like manner by means of a rock-rod, E2, having corresponding top and bottom arms, F2 G2, pivotally connected to the said spout, and connected to the bottom end of the other arm 12 by a pivoted The ,rod, 112, as shown, by which the sponts T2 V2 are connterbalanced. The tailings-spont V2 opens into the casing 1213 of the inclined elevator-belt 12, which latter works around a pulley, ;12, on the end of the shaft F2, and around a top pulley, K2, fixed on a shaft, L, that is jonrnaled at the top of the casing H3 and has its end projecting therefrom. The casing. H3 is provided at the sides of its month M3 with lateral lugs or fianges N2, having perforations O2, through which slide curved rods P2 P2, projecting from lthe rear end of the trough Q2, which latter comes under the month M3 and extends forward to the hopper J. The trough Q2 is pivotally connected by a pitman, R3, with a crank-wheel, S3, on, the end of the shaft L,

and as the said shaft revolves the said trough w is reciprocated on the rods P2122 to convey the chaif and tailings from the elevator-belt to the hopper J. TheV trough is provided with a longitndinally-extending guide-rod, T2, on its nnderl side, which works in a guide-block, U2, secnred on top the feeding-cylinder chamber.

The operation and advantages of my invention' are obvious. 1t is very simple and eflicient in operation, and its different reciprocating parts have a general connterbalanced movement by which the machine will work much more easily and satisfactorily and with less wear upon the parts.
